Scientists may have uncovered a new class of tunable quantum particles that break the universe’s long-standing boson-versus-fermion rule. Credit: AI/ScienceDaily.com Physicists have traditionally sorted all elementary particles in our three-dimensional universe into two categories: bosons and fermions. Bosons mostly include particles that carry forces, such as photons, while fermions make up ordinary matter, including electrons, protons, and neutrons. That simple division starts to break down
